ABSTRACT
The Internet of Things (IoT) happens to be one of the most promising technologies in recent research. In case of the cloud-enabled Internet of Things, it offers multitenancy as one of its characteristics. Simultaneously securing such data and offering a good access control policy over the cloud without compromising on user data and privacy is a challenging task. This chapter discusses an extensive overview of existing access control policies proposed in the context of the cloud and IoT and outlines the possibilities of future research directions. The IoT infrastructure collects data and stores them over networked servers like the cloud. The chapter also discusses the primitives used in defining secure access control policies. Role-based access control methods have been predominantly used since the UNIX operating system days to specify permission to a specific set of users to access files.
